Early Fetal Heart Development

Angiogenic Cell Clusters are the building blocks of what will become a fetal heart tube known as the primitive heart tube. The primitive heart tube develops around three to four weeks and goes through an incredible transformation transforming into a four-chamber heart. The heart begins to beat on approximately the twenty-second day, which corresponds to the 5th week of 40 week pregnancy based on LMP.

Is it a Boy or a Girl, the old wives tale suggest that fetal heart rates above 140 bpm are a sure sign it's going to be a girl and fetal heart rates below 140 bpm mean it's a boy. This "theory" is based on the fact that girls have higher metabolisms than boys, unfortunately there is no statistical proof to verify this tale and in fact the evidence indicates that therre is no relationship between heart rate and sex.
